A fluid mixing system includes a flexible bag having a first end, an opposing second end, and an interior surface bounding a compartment; a retainer coupled to the second end of the flexible bag, the retainer having a retention cavity formed thereon that communicates with the compartment of the flexible bag; and an elongated member having a first end rotatably coupled to the first end of the flexible bag and an opposing second end freely disposed within the retention cavity of the retainer so that the second end of the elongated member can rotate within the retention cavity relative to the retainer.

A fluid mixing system includes a flexible bag having a first end, an opposing second end, and an interior surface bounding a compartment. A first rotational assembly includes a first casing mounted to the first end of the flexible bag and a first hub rotatably mounted to the first casing. A second rotational assembly includes a second casing mounted to the second end of the flexible bag and a second hub rotatably mounted to the second casing. An elongated member has a first end coupled with the first hub and an opposing second end coupled with the second hub, the connector being flexible and having a uniform flexibility along its entire length. A first impeller is mounted to the connector.

A method for reconstitution of substances includes a liquid container having a pre-determined volume of diluent and a powder container having a corresponding pre-determined amount of powder to be reconstituted. The method allows an individual to safely reconstitute the powder into a liquid solution having the desired concentration without measuring or potential spillage. The powder container includes a female threaded connection designed for liquid-tight attachment to the liquid container and further includes a breakable membrane seal which, when broken by the distal end of the liquid container, creates an orifice for the diluent to enter the powder container to reconstitute the powder and thereafter be displaced into the liquid container for use. Before the membrane seal is broken, the pre-determined amount of powder partially occupies the powder container chamber.

The present invention relates to a portable liquid mixing device capable of mixing different types of various liquids, and the different types of various liquids may include various beverages. The present invention includes a plurality of containers configured to contain respective specific liquids, a selection unit configured to select any one of the plurality of containers, a control unit configured to control the introduction of a selected liquid into a mixing container, and a mixing unit configured to mix various liquids introduced into the mixing container. According to the present invention, different types of liquids may be mixed together. In particular, beverages having various flavors are put into respective containers, mixed together and then drunk. Furthermore, a scale is marked on the surface of the mixing container, and thus the amount of liquid may be accurately measured, so that liquids may be mixed at an accurate ratio.

To sum up, by using the shaker for mixing liquids (1-7) (e.g. shampoo, soap, etc) with water right before use, an optimal dose of the liquid is used and appropriate solution is used. A dissolved mixture is applied to the hair/body to most significant part immediatelythe hair roots and the scalp. It works beneficial for the hair, especially the hair ends, preventing dry and split ends as the e.g. shampoo is not applied directly. The mixture is distributed more evenly throughout the hair, without adding additional water and washing out the unused shampoo. The foam evolves quicker and is greater, which makes the washing easier. The shaker enables the user to use multiple liquids at once if needed. The amount of the liquid used is decreased to an optimal dose for the user and is therefore also eco-friendly, as no excessive amount of liquid is used. The invention enables the user to close tap water/shower during use and therefore uses less water and is eco-friendly. With same advantages the shaker is used in pet care and with other liquids.

Miniature stirred tank bioreactor and system; the bioreactor configured for single use culturing providing unobstructed culturing volume with sensors, probes and ports using minimally invasive placement in-wall or across the wall methods; the bioreactor further capable of containing scaffolds and features for culturing cells and tissue, including structures providing surfaces for cell growth, and screens for retaining microparticles during media exchange.

A device for storing first and second ingredient materials, mixing the ingredient materials to form an adhesive material and dispensing the adhesive material. The device comprises: a nozzle for dispensing the third material; a first container adapted to store a first ingredient material and mix the first ingredient material with a second ingredient material; a second container disposed within the first container, and moveable between a storage position in which a second ingredient material is stored in the second container and a mixing position in which the second ingredient material is moved to the first container; a mixer that longitudinally extends into the first and second containers; a handle alternatively coupled to the mixer to mix the first and second ingredient materials or to the second container to move the second container to a dispensing position to dispense the third material. During use, the first container is rotated causing the second container to move relative to the first container and the second material to flow into the first container for mixing. After mixing, the handle is uncoupled from the mixer and coupled to the second container to dispense the third material from the nozzle. Embodiments are also described herein for a method of making the device and a method of using the device.

In a stirred tank chemical reactor the mean age of the reactor contents affects a number of properties of the product, including for example the homogeneity of the product. The mean average age of the reactor contents can be determined by constructing a transparent model of the reactor and filling it with a fluid containing a fluorescent dye and having flow properties comparable to those of the reactor in use. A light is shone on the fluid as it is stirred under reaction conditions and a clear fluid flow into the model. Pictures are taken of the reactor contents and the mean fluid age of the contents of the model are determined relative to the exit age of the contents. This approach can be applied to determine for example which reactor ports to use, what agitator to use, what flow rates to use to improve reactor function.
